EXHIBIT "D" <br /> MINING PLAN <br /> 6.4.4 The Mining Plan is for a 112 Conversion Permit Application: <br /> (a) Description of the methods of mining in each stage of the operation as related <br /> to any surface disturbance on affected lands: <br /> The proposed expansion to a 112 Regular Mining Operation will be an intermittent <br /> mining operation,mining less than 180 days per year, in a typical year. However, due to <br /> County project needs,the operation may, on occasion,operate more than 180 in any <br /> given year. <br /> Mining methods will be consistent throughout the life of this mining operation. This will <br /> be an open pit mining operation. The post mining reclamation plan is to return the site to <br /> rangeland. <br /> Topsoil will be stripped and stockpiled for use during reclamation. If there is any excess <br /> overburden, it may be sold or given away. <br /> This will be a dry mining operation since excavation operations will occur above the <br /> regional ground water table. Primarily, scraper(s), front-end loader(s), excavator(s) and <br /> haul trucks or other similar equipment will remove the topsoil,overburden and aggregate. <br /> Material may be immediately sold, or placed in stockpile(s) (up to 3,000 tons). <br /> Other Equipment <br /> Equipment Type: <br /> Screens for sizing And other equipment as may be necessary <br /> for efficient pit and processing operations <br /> Scales for truck weights <br /> Topsoil and overburden, if any, will be placed in stockpiles until needed for site <br /> reclamation. Processing(crushing and screening) of the excavated material will occur as <br /> needed. Any processing which might occur will be by portable equipment, brought onto <br /> the site, and will be placed in a mined out area of the pit. The Pre-mine/Mine Plan Map <br /> provides the locations of topsoil stockpiles during the initial phases. Topsoil from Phase <br /> A-1 and A-2 will be stockpiled into adjacent Phase B topsoil stockpiles. Topsoil from <br /> Phase A-3 will be placed adjacent to Phase A-1 for its reclamation. As each new phase is <br /> initiated,topsoil will be cycled to a previous mined and graded phase for phase <br /> 22 <br />
